Overview: Chocolate Zucchini Cake Components
This decadent cake is made with contemporary summer season zucchini and pantry fundamentals. Do you know that cocoa powder can dry out baked items rather more than flour? To compensate for this, we guarantee there’s loads of added moisture within the cake batter.
Let’s assessment a number of key elements:
- Unsweetened Pure Cocoa Powder: Cocoa powder takes the place of some flour. Simply as in my common chocolate cake recipe, be sure you’re utilizing pure unsweetened cocoa powder as a substitute of dutch-process cocoa powder.
- Espresso Powder: Espresso powder accentuates the chocolate taste. Whereas optionally available, I extremely advocate utilizing it. The chocolate zucchini cake received’t style like espresso. Somewhat, the espresso powder helps deliver out the extreme chocolate taste. We use it in chocolate zucchini bread and on this chocolate cake roll, too. You will discover espresso powder within the espresso aisle on the grocery retailer or on-line.
- Oil: Oil provides moisture. You may attempt changing *some* of the oil with unsweetened applesauce. I’ve carried out this with chocolate desserts and muffins and the result’s fantastic, however I don’t advocate changing all of it. Whatever the zucchini inside, this isn’t well being meals, it’s dessert. Don’t make it one thing it’s not!
- Eggs: 4 eggs bind all the pieces collectively and add moisture. Keep in mind that room temperature elements are essential.
- Bitter Cream: Similar to in chocolate peanut butter cake, you should use bitter cream or plain yogurt. Both add moisture.
- Zucchini: Use a whopping 3 cups of shredded zucchini on this recipe. Testing how a lot we will get away with… with out truly tasting it! Zucchini is pure magic in desserts—nothing however flavorless moisture. Similar goes with my zucchini bread and zucchini muffins, too!
Non-obligatory Chocolate Chips: For mega chocolate taste, add chocolate chips to the batter. They’re key to these melty pockets of chocolate in every slice. I exploit semi-sweet chocolate chips (similar to in my peanut butter chocolate chip zucchini bread), however mini chocolate chips and even darkish chocolate chips pair splendidly, too.


Let Me Present You The way to Make It:
This chocolate zucchini cake comes collectively shortly and simply, similar to my common zucchini cake. Merely whisk the dry elements in a single bowl and beat the moist elements collectively in one other bowl. Mix the moist and dry elements, then add the chocolate chips. The cake batter will likely be barely thick because of the entire zucchini! Divide the batter between two 9-inch cake pans or you can also make 1 / 4 sheet cake utilizing a 9×13-inch cake pan. See my recipe notes for particulars.
